This pr adds initial support for creating a cross-compile tool chain for arbitrary architectures. For now only `aarch64` and `riscv64` are implemented, but simlpy adding another architecture to the list of supported platforms in each package should mostly work with minimal patches.
In order to build native gcc for aarch64, you can run
```
nix-build --expr '((import ./tidepool).packages.foundation.gcc.versions."13.2.0-stage4".package.extend { platform = { build = "aarch64-linux"; host = "aarch64-linux"; target = "aarch64-linux"; }; }).package'
```
or
```
nix-build tidepool -A packages.foundation.gcc.latest.packages.aarch64-linux.aarch64-linux.aarch64-linux
```
Running this command:
- Uses [foundation](https://git.auxolotl.org/auxolotl/foundation) to bootstrap i686 gcc
- Incrementally bootstraps x86_64 gcc from i686
- Runs through the same incremental process, but this time using x86_64 gcc we previously built to bootstrap aarch64
- Build the final native aarch64 gcc
